Choose the wrong statement about the regenerative vapour power cycle employing bled steam form feed water heating:

What is the specific steam consumption (in kg/kWh) of the Rankine cycle based on net output if the enthalpies at turbine inlet and exit are 3200 kJ/kg and 2050 kJ/kg respectively. Specific work by pump is 1.5 kJ/kg.

For a Rankine cycle with reheating, which of the following statements are correct?

I. Thermal efficiency will decrease

II. Average temperature of heat addition will increase

III. Steam at turbine exit becomes drier

A steam power cycle with single-stage regeneration is shown below:

An open feed water heater is used for regeneration purpose.

If the bleed from turbine at state ‘2’ is 30%, what will be the enthalpy of steam after exiting from regenerator?

If a reheater is added to a Rankine Cycle then usually

Rankine cycle consists of __________.
